Chapter 5 Turn Up Network
NTP-A225 Open-Ended Path Protection Acceptance Test
Step 4 Click the Conditions tab.
a. Verify that no unexplained conditions appear on the network. If unexplained conditions appear,
resolve them before continuing. Refer to the Cisco ONS 15454 Troubleshooting Guide if necessary.
b. Complete the “DLP-A516 Export CTC Data” task on page 22-6 to export the conditions
information.
Step 5 On the network map, double-click the node that you logged into in Step 1.
Step 6 Create a test circuit from that node to the OC-N trunk (span) cards on the nodes that connect to the
third-party network. For example, in Figure 5-11 on page 5-32, a circuit is created from Node 1 to the
Slot 5 OC-N card at Node 2, and a secondary circuit destination is created on the Slot 12 OC-N card at
Node 3. For circuit creation procedures, complete one of the following:
• For DS-1 circuits, complete the “NTP-A181 Create an Automatically Routed DS-1 Circuit”
procedure on page 6-6. When you set the circuit state, choose IS and check the Apply to drop ports
check box.
• For DS-3 circuits, complete the “NTP-A184 Create an Automatically Routed DS-3 Circuit”
procedure on page 6-18. When you set the circuit state, choose IS and check the Apply to drop
ports check box.
• For OC-N circuits, complete the “NTP-A257 Create an Automatically Routed OC-N Circuit”
procedure on page 6-38. When you set the circuit state, choose IS and check the Apply to drop
ports check box.
Step 7 Create a circuit within the third-party network from ONS 15454 connection ports to the second set of
ONS 15454 connection ports on both path protection spans. Refer to the third-party equipment
documentation for circuit creation procedures.
Step 8 Repeat Step 6 to create a second circuit at the terminating node on the other side of the third-party
network. In Figure 5-11, this is Node 6. However, this circuit will have two sources, one at
Node 4/Slot 12, and one at Node 5/Slot 5. The destination will be a drop card on Node 6.
Step 9 Configure the test set for the test circuit type you created:
• DS-1—If you are testing a DS-1 that is not multiplexed, you must have a DSX-1 panel or a direct
DS-1 interface into the ONS 15454. Set the test set for DS-1. For information about configuring
your test set, consult your test set user guide.
• DS-3—If you are testing a clear channel DS-3, you must have a DSX-3 panel or a direct DS-3
interface into the ONS 15454. Set the test set for clear channel DS-3. For information about
configuring your test set, consult your test set user guide.
• DS3XM-6/DS3XM-12—If you are testing a DS-1 circuit on a DS3XM-6 or DS3XM-12 card you
must have a DSX-3 panel or a direct DS-3 interface to the ONS 15454. Set the test set for a
multiplexed DS-3, then choose the DS-1 to test on the multiplexed DS-3. For information about
configuring your test set, consult your test set user guide.
• OC-N—If you are testing an OC-N circuit, set the test set for the applicable circuit size. For
information about configuring your test set, consult your test set user guide.
Step 10 Verify the integrity of all patch cables that will be used in this test by connecting one end to the test set
Tx connector and the other end to the test set Rx connector. If the test set does not run error-free, check
the cable for damage and check the test set to make sure it is set up correctly before continuing.
Step 11 Create a physical loopback at the circuit destination card:
a. Attach one end of a patch cable to the destination port’s Tx connector.
b. Attach the other end to the port’s Rx connector.
